Care of dying adults in the last days of life .

Care of people in their last days of life should be based on compassion, respect and, wherever possible, on research evidence. Previously the Liverpool Care Pathway attempted to facilitate this but it was withdrawn after an independent government report found that its uncritical implementation could lead to poor care. This Concise Guideline overviews NICE Clinical Guideline (NG31), which addresses: recognising dying; communication and shared decision making; maintaining hydration; and pharmacological symptom control, including anticipatory prescribing. Doctors may need to change their attitudes to care of dying people and those important to them. Specific areas where practices will need to reflect the individualised approach to care are highlighted. Limitations of the guideline are discussed. Potential barriers to implementation include need for further training and 24/7 availability of specialist support to front-line clinicians.

Paracetamol: not as safe as we thought? A systematic literature review of observational studies.

OBJECTIVES: We conducted a systematic literature review to assess the adverse event (AE) profile of paracetamol. METHODS: We searched Medline and Embase from database inception to 1 May 2013. We screened for observational studies in English, which reported mortality, cardiovascular, gastrointestinal (GI) or renal AEs in the general adult population at standard analgesic doses of paracetamol. Study quality was assessed using Grading of Recommendations Assessment, Development and Evaluation. Pooled or adjusted summary statistics were presented for each outcome. RESULTS: Of 1888 studies retrieved, 8 met inclusion criteria, and all were cohort studies. Comparing paracetamol use versus no use, of two studies reporting mortality one showed a dose-response and reported an increased relative rate of mortality from 0.95 (0.92 to 0.98) to 1.63 (1.58 to 1.68). Of four studies reporting cardiovascular AEs, all showed a dose-response with one reporting an increased risk ratio of all cardiovascular AEs from 1.19 (0.81 to 1.75) to 1.68 (1.10 to 2.57). One study reporting GI AEs reported a dose-response with increased relative rate of GI AEs or bleeds from 1.11 (1.04 to 1.18) to 1.49 (1.34 to 1.66). Of four studies reporting renal AEs, three reported a dose-response with one reporting an increasing OR of ≥30% decrease in estimated glomerular filtration rate from 1.40 (0.79 to 2.48) to 2.19 (1.4 to 3.43). DISCUSSION: Given the observational nature of the data, channelling bias may have had an important impact. However, the dose-response seen for most endpoints suggests a considerable degree of paracetamol toxicity especially at the upper end of standard analgesic doses.

The definition of acute kidney injury and its use in practice.

Acute kidney injury (AKI) is a common syndrome that is independently associated with increased mortality. A standardized definition is important to facilitate clinical care and research. The definition of AKI has evolved rapidly since 2004, with the introduction of the Risk, Injury, Failure, Loss, and End-stage renal disease (RIFLE), AKI Network (AKIN), and Kidney Disease Improving Global Outcomes (KDIGO) classifications. RIFLE was modified for pediatric use (pRIFLE). They were developed using both evidence and consensus. Small rises in serum creatinine are independently associated with increased mortality, and hence are incorporated into the current definition of AKI. The recent definition from the international KDIGO guideline merged RIFLE and AKIN. Systematic review has found that these definitions do not differ significantly in their performance. Health-care staff caring for children or adults should use standard criteria for AKI, such as the pRIFLE or KDIGO definitions, respectively. These efforts to standardize AKI definition are a substantial advance, although areas of uncertainty remain. The new definitions have enabled the use of electronic alerts to warn clinicians of possible AKI. Novel biomarkers may further refine the definition of AKI, but their use will need to produce tangible improvements in outcomes and cost effectiveness. Further developments in AKI definitions should be informed by research into their practical application across health-care providers. This review will discuss the definition of AKI and its use in practice for clinicians and laboratory scientists.

Education for public health capacity in the nursing workforce: findings from a review of education and practice issues.

Current NHS policy highlights the importance of public health as a strategy to reduce health inequalities and to promote the health of communities, and nurses are recognised as key contributors to the public health function. Changes are also taking place in pre- and post-registration nurse education curricula, in the wake of recent education policy recommendations. However, progress towards effective educational preparation for nurses' public health function and the educational issues involved, has not been systematically charted. The study reported below investigated the adequacy of public health education and the issues involved in effective education practice through a literature review and interviews with key informants. Findings highlight issues concerned with programme outcomes, practice placement experiences, and continuing professional development. Findings are discussed, and implications and recommendations for educational and other key stakeholders are outlined.
